Add print layout with ability to hide

This PR aims to resolve issue #815.

I've added a print layout to make the search results more readable when printed. Here is the result for printing all pages.

print-all.pdf

With the ability to fold certain content, I used this feature to completely hide folded sections in print. Here’s an example where the "Graphical Overview" section is folded.

Thank you Joko - the way you hide the things is definitely the way to do it - thanks for that initiative

what would happen if an American tries printing? (they are typically US Letter paper size users)
